Asking things like Ampere's Law makes sense because W/A one day (but
not today apparently) will answer these questions/searches.
Remember it is a computational knowledge engine. So it could provide
an explanation of the law (taken from wikipedia perhaps) and present a
form where you could input some of the variables appearing in Ampere's
law and solve for the missing ones.
In any case, w/a would like has the ambition to appear "sentient".
You get sensible answers to the following questions/queries:
What is your name?
How old are you?
What are you?
Wolfram Alpha (already classified as an historical event!)
Mathematica (but elegantly ignores the existence of other CAS systems
out there :-). Try the most popular ones )
Try them yourself!
W/A has also many "easter eggs" hidden inside (see later), which will
amuse you.
So if WRI people spent their time hard-wiring this knowledge, why not
the basic laws of physics?
I think they should be next.
Also, somewhat disappointingly for me, has no clue (yet) what is
Category Theory
while it could - at least - point us to:
http://mathworld.wolfram.com/topics/CategoryTheory.html
without exiting the "Wolfram online universe"
